For which type of construction are noncombustible materials mandatory?

1. Type I

2. Type II

3. Type III

4. Type IV

The correct answer is: Type I

Noncombustible materials are required for Type I construction, which is characterized by its high resistance to fire. This type of construction typically involves the use of materials such as concrete and steel, which do not ignite or burn, thus providing enhanced safety against fire hazards. Type I construction is often associated with high-rise buildings and other structures where fire safety and structural integrity are crucial due to the potential occupancy and use of the building. Type II construction, while also requiring materials with limited combustibility, allows for the use of some noncombustible materials alongside combustible ones. Types III and IV construction are generally more permissive regarding the use of combustible materials, with Type III allowing for combustible framing covered with noncombustible materials, and Type IV construction utilizing heavy timber that can present fire risks.
